Hey, I can work with this idea. First, there really is no 'off' mode
for wrapped because that is aligned. What we could do is to have:

\pset format wrapped display

affect only output to the screen, using the screen width, and:

\pset format wrapped nnn

affect output to the screen and file/pipes.
